*** www.factlab.com ***

In order to play a game, you can elect to play either anonymously or by logging in with a Facebook account. You can create a new game by pressing the Create game button on the home page. You can choose a level of difficulty, the number of seconds a question should last, the number of questions for the game, the game theme and whether you want to challenge somebody or play a single player game.

In the single player mode, you will be provided with a list of questions reflecting the choices at the previous step, each having 4 possible answers. After finishing the game, you will get the list of questions along with a mark to indicate if the answer was correct or not. You can check the facts by sending them to an email or post them on Facebook, play another game or exit the game mode to the home screen.

If choosing the challenge mode, you can select an opponent from the Facebook friends (if logged in with a Facebook account), search an opponent by username or let the application provide an opponent with a similar score. After finishing the game, it will be displayed in the list with the Waiting status. If the opponent does not respond to the challenge, after some time the Waiting status will change, offering you the ability to send a Poke, that is to notify the opponent that he should answer the challenge. The game will take place as in the single player mode.

When being challenged by another player, you will receive a notification with the details of the game. The game will appear as having the Accept option, meaning that you should agree to play with the opponent. At the end of the game you will get the game results, that includes also the number of correct answers, the time bonus and difficulty bonus for each player. Also you will be notified if you lost or won the game.

Factlab trivia uses a scoring mechanism based on the Elo rating system. That means that players with a similar score will have a similar rating. The winning player takes rating points from the losing player. Moreover, if a player with a lower rating will win against a player with a higher rating, the difficulty bonus will be much higher for the player with the lower rating.
